在《格林多前書》第五章和第六章中，保祿責備了信徒。我們今天讀到的是第一個責備，即亂倫關係，這為猶太人和外邦人所憎惡。

保祿的反應非常強烈：他設立了一個審判台，他的靈就在那裡，這個審判台判處犯亂倫罪的人兩項刑罰：與教會分離，以及交在撒殫手中（可能類似於《約伯傳》中所描述的：撒殫要使這個人像約伯一樣，在肉體上遭受各種苦難）。然而，其目的是為了這個人在末日得救。

保祿接著做了一個概括性的評論：一個人如果一邊為自己的信仰感到驕傲，一邊又做出與信仰相悖的行為，這是不可能實現的（這一點對猶太人來說非常清楚，但對外邦人來說又如何呢？）。

保祿將基督徒的生活與逾越奧蹟連結起來：我們的生命必須與耶穌合而為一，我們的選擇必須與祂的選擇一致。

In Chapters 5 and 6 of the First Letter to the Corinthians, Paul reproaches the believers. We read today the first reproach, the case of an incestuous relationship, which was abhorred by both Jews and Gentiles.

Paul’s reaction is very strong: he creates a tribunal, where he is present in spirit, and this tribunal condemns the incestuous man to two punishments: separation from the community and delivery into the hands of Satan (possibly in the way meant in the Book of Job: Satan is supposed to have this man suffer all kinds of tribulations in the flesh, as Job suffered). The purpose however is the salvation of this man in the last day.

Paul then makes a general comment: to be proud of one’s faith while having a behavior contrary to it is not possible (This was very clear for the Jews but what about the pagans?).

He connects the life of Christians to the Paschal Mystery: our life must be one with Jesus, our choices need to be the same as His choices.
